Specification of Letters Patent.

Patented May '7, 191 8.-

Application filed November 21, 1917. Serial No. 203,255.

To all whom it may concern Be it known that I, MAXWELL B. F more, a citizen of the United States, residing at Corona, in the county of Riverside and State of California, have invented new and useful Improvements in Portable and Knockdown Storage-Bins, of which the following is a specification.

My object is to provide footings, wall plates, and interlocking binding bars, so that a temporary bin may be constructed of any desired ground area and of any desired height, used the desired length of time, and then torn down to be re-set up in another place and ofany desired different area and height, and my invention consists in the novel features herein shown, described and claimed.

Figure 1 is an elevation of a knock-down storage bin constructed in accordance with the principles of my invention.

Fig. 2 is a vertical sectional detail upon an enlarged scale upon the line 22 of Fig. 1. I

Fig. 3 is a horizontal sectional detailstill further enlarged and taken upon the line 33 of Fig. 1.

Fig. 4 is a perspective of one of the interlocking binding bars.

Fig. 5 is a plan of one of the footings.

In preparing to construct a storage bin, the ground will be leveled to form a suitable floor for the material to be stored and the footings 1 are then arranged upon the floor in a circle surrounding the storage area. This circle may be large or small, as desired. The footings 1 each comprise a base block 2 of wood or other material, a base plate 3 of metal secured to the upper face of the block, and a retaining flange 4 extending upwardly from the plate 3. f

A tier of wall plates 5 is placed end to endupon the footings 1 inside of the flanges 4, and as the wall plates are placed in position the interlocking binding bars 6 are applied to the upper edges.

Each of the binding bars 6 comprises a metal plate bent to form the inside retaining flange 7, the inside return bend 8, the central supporting web 9, the outside return bend 10, the outer retaining flange 11, and the interlocking hooks 12 and 13 extending from the ends of the flange 11. The binding bars are substantially the same length as the wall plates and when assembled it is preferable that the joints formed by meeting lower edges of the ends of the wall plates be'located intermediate of the joints formed by meeting ends of the binding bars. The wall plates are curved, more or less, in plan, according'to the ground area of the bin to becoustructcd, and thebinding bars are correspondingly cuifiled so as to fit the wall plates reasonably we 7 Then a tier of wall plates 5 has been placed upon the footings and a tier of the interlocking binding bars 6 placed inposition upon theupper edges of the wall plates, the binding bars make a band like a hoop to hold the wall plates in place. The upper I edges of the wall plates 5 fit between the web 9 and the outer retaining flange 11 against the return bend 10.

A second tier of wall plates 14: is then placedin first tier of interlocking binding bars, the

wall plates 14 passing downwardly between the web 9 and the inner retaining flange 7 against the return bend 8. Then a second tier 15 of the interlocking binding bars is placed in position upon the upper edges of the wall plates 14 and then a third tier 16 of wall plates is applied to the second tier of binding bars, and so on up to the desired height.

The tiers of wall plates are staggered in cross-section, as shown in F ig. 2, alternate ones, as 14, being inside, as 5 and 16, being outside.

If the bin is to be built upon a solid piece of ground or upon a good floor, the footings 1 may be omitted, or, if desired, the footings 1 may be embedded in the ground or concrete or other floor so that the lower edges of the lower tier of wall plates will form close joints with the ground or floor.

The interlocking binding bars are Z-shaped in cross-section and may be identical in construction. The tier 6 of binding bars may be one side up with the hooks on the outside and the tier 15 of binding bars the other side up with the hooks on the inside, or the binding bars may be made right and left so that the hooks may be all inside or all outside.

My knock-down storage bin may be used for temporarily. storing grain at threshing time and it may also be used for storing sand, plaster, crushed rock, coal, and other material in doing contract work where the material is to be stored for a short time and then used and the bins no longer needed, and

position to be supported by the.

and the other half, I

the bin may be used for many other purposes, depending upon the location of the requirements.

I claim:

1. An interlocking binding bar Z-shaped in cross-section and having hooks extending from its ends.

2. A series of interlocking binding bars, each bar being Z-shaped in cross-section and having interlocking hooks extending from its ends, so that the bars may be hooked together to form a continuous band.

3. A series of Wall plates fitting together end to end to form a tier, and a series of interlocking binding bars fitting the upper edge of the tier of plates to form a continuous band. i

4. A series of Wall plates fitting together end to end to form a tier, and a series of interlocking binding bars fitting together end to end and fitting the upper edge of the tier Copies of this patent may be obtained for of plates to form a continuous band and hold the plates together and adapted to receive another tier of plates.

. 5. A knock-down bin comprising a plurality of series of Wall plates; the plates of each series fitting together end to end; and a series of interlocking binding bars for each series of plates; the binding bars being Z-shaped in cross-section and having interlocking hooks extending from their ends.

6. A series of interlocking binding bars; each bar being Z-shaped in cross-section and curved in plan and having interlocking hooks extending from its ends.

7. A knock-down bin "comprising Wall plates, and interlocking binding bars forming bands to hold the plates together.

In testimony whereof I have signed my name to this specification.
